[PATCH] sparc32: fix build failure for arch_jump_label_transform

[Paul Gortmaker]

In arch/sparc/Kernel/Makefile, we see:

   obj-$(CONFIG_SPARC64)   += jump_label.o

However, the Kconfig selects HAVE_ARCH_JUMP_LABEL unconditionally
for all SPARC.  This in turn leads to the following failure when
doing allmodconfig coverage builds:

kernel/built-in.o: In function `__jump_label_update':
jump_label.c:(.text+0x8560c): undefined reference to `arch_jump_label_transform'
kernel/built-in.o: In function `arch_jump_label_transform_static':
(.text+0x85cf4): undefined reference to `arch_jump_label_transform'
make: *** [vmlinux] Error 1

Change HAVE_ARCH_JUMP_LABEL to be conditional on SPARC64 so that it
matches the Makefile.

[This appears to be nothing new ; I checked out 3.0 and the
 same Makefile/Kconfig mismatch existed back then as well.]

Applied.
